Feedback - installing Linux SDK on Ubuntu 9.04

[prf]

Some feedback about installing the latest version of the Linux SDK under Ubuntu 9.04 and hopefully might help others with a similar problem.

I recently purchased an Xport Pro and Development board. I applied all the dendencies as detailed in the Linux SDK User Guide un Ubuntu 9.04.

The install.sh script installed all the software correctly and I was able to run 'make menuconfig'. I could set the Vendor/Product Selection to Lantronix and Xport Pro, and set Customize Kernel Settings and Customize Application/Library Settings in Kernel/Library/Defaults section. On exit-ing and saving the configuration, the program stopped with the following error:

[email protected]:~/xport_SDK$ make menuconfig
cd /home/prf/xport_SDK/linux; make menuconfig
make[1]: Entering directory `/home/prf/xport_SDK/linux'
config/mkconfig > Kconfig
KCONFIG_NOTIMESTAMP=1 /home/prf/xport_SDK/linux/config/kconfig/mconf Kconfig


*** End of Linux kernel configuration.
*** Execute 'make' to build the kernel or try 'make help'.

./.oldconfig: 1: -e: not found
./.oldconfig: 2: -e: not found
./.oldconfig: 3: -e: not found
./.oldconfig: 4: -e: not found
make[1]: Leaving directory `/home/prf/xport_SDK/linux'
[email protected]:~/xport_SDK$

After much head scratching, the problem was narrowed down to the setconfig script under <sdk_installation>/linux/config:-

**************************************************
#
# remove line containing $1 append line $2 to file in $3
#
replace_line()
{
TMPR="/tmp/setconfig.$$"
if [ -f "$3" ]
then
cat "$3" | grep -v "$1" > "$TMPR"
else
touch "$TMPR"
fi
echo -e "$2" >> "$TMPR"
cp "$TMPR" "$3"
rm -f "$TMPR"
}

**************************************************
If I edit the line echo -e "$2" >> "$TMPR" to echo "$2" >> "$TMPR" all seems to work and I can run 'make menuconfig' successfully, make changes to the kernel and applications and use 'make' to start compilation.
I guess that the Ubuntu version of 'echo' doesn't support the -e option correctly. I experienced the same problem using Ubuntu 8.04 and 9.1.

I had to replace default /bin/sh link with bash to solve this.

I ran into the same thing on Kubuntu 9.10. Thanks for the post. I simply fixed it with a symlink /bin/sh -> /bin/bash

Symlink alteration - Ubuntu 9.04

Sorry for delay replying - been away for a couple of weeks.
Thanks for your solutions, I tried changing the symlink as suggested but it seemed to already set. Not been able to make it work so far, perhaps I am updating the symlink incorrectly?

Pete, are you re-running the install.sh script after you make the symlink? If you do "ls -l /bin" or some such, you should see something like "/bin/sh -> /bin/bash", if you see that, you're good, you just need to run the install.sh script again after.

By default Ubuntu now uses dash instead of bash, there is much debate about the pros and cons on the Ubuntu forum, but also a solution how to swap over to bash again. Although this may impact on other aspects ie speed and compilation times.

As you suggested earlier, I found that /bin/sh was linked to /bin/dash.
I altered this to point to /bin/bash by doing 'sudo dpkg-reconfigure dash' and accepting the 'No' option.

It can be altered back to 'dash' by running dpkg-reconfigure dash again.
Many thanks for the help

That's good info, Pete, I didn't know about dpkg-reconfigure, thanks. It's probably the more correct way of doing it than just making the symlink because your way, it will persist through upgrades and what what have you.
